Rare earth (RE)-substituted magnesium–zinc ferrite (Mg0.5Zn0.5RExFe2–xO4) nanoparticles with different RE elements (Y, La, Ce, Pr, Nd, Gd and Yb) contents (x = 0–0.1) were synthesized via coprecipitation of metal hydroxides as the precursor, followed by calcination. Their crystal structures characterized X-ray diffraction (XRD) analysis, confirming that RE-substituted Mg–Zn ferrites had a singl...

Nickel–zinc ferrites are some of the most interesting soft magnetic materials. They have been extensively used in a number of electronic devices because of their low magnetic coercivity, low eddy current related to their high electrical resistivity, and they are especially suitable for high–frequency applications (large permeability). New low-temperature synthesis methods have been developed to...

The effect of Zn substitution on the DC electrical resistivity, AC electrical conductivity and microstructure of V2O5 doped Zn(1-x)NixFe2O4 with x=0.0, 0.1, 0.2, 0.3, 0.4 (5 samples) were prepared by conventional ceramic technique has been investigated. The structural characterization of nickel-zinc ferrites were done by X-ray diffraction technique. Micro-structural and morphological studies we...

Nanocrystalline zinc ferrite (ZFO) has been synthesized from metal acetylacetonates by microwave irradiation for 5 min in the presence of a surfactant. The as-prepared material is ZFO and has been subjected in air to conventional furnace annealing and to rapid annealing at different temperatures. Both annealing protocols lead to well-crystallized ZFO, with crystallite sizes in the range 8–20 nm...
